This is a fun worksheet for the Christmas season where students practice their basic addition and subtraction skills on a Christmas tree. They start at the bottom of the tree and work their way up, writing answers in triangles as they go. The final answer goes at the top of the Christmas tree. The only way to get the correct answer at the top of the tree is to have correct answers in all the other triangles. Rows where the numbers are added alternate with rows where the numbers are subtracted.
The majority of numbers to be added or subtracted have 3 digits, although there is one 4-digit number, two 2-digit numbers, and one 1-digit number.
The answer key is included.
